The invention simplifies the fabrication process by enabling the simultaneous formation of the first electrode and the source and drain electrodes from the same material. This reduces the number of processing steps, improves manufacturing efficiency, and potentially enhances device uniformity. The first electrode may function as a gate electrode, while the source and drain electrodes are typically used to control current flow in the semiconductor channel. By using the same material for these electrodes, the method avoids the need for separate deposition and etching processes, reducing material waste and processing time. The invention is particularly useful in large-area electronics, such as displays or sensors, where cost-effective and scalable manufacturing is critical. The simultaneous formation of these electrodes ensures consistent electrical properties and reduces potential misalignment issues between the electrodes.
